Did you know this earthquake happened on the same day in history ?Italy, 2009 – Magnitude : 6,3 – 308 people killedThe quake occured on 3:32 local time, when most of the people were sleeping. More than 15.000 buildings were destroyed by the quake and triggered landslides. More than 55.000 people got homeless, more than thousand were injured. Most of the damage occured in L’Aquila, a town very close to the epicenter. Many parts of the town were damaged. The mainshock was felt as far as Nuremberg (Germany) and Podgorica (Montenegro). One strong afterhock with M 5.5 killed one person and damaged additional buildings in L’Aquila on April 7th 2009. A large number of foreshocks preceded the main shock weeks before. Many people were scared by these small shocks, expecting a larger one. Scientists tried to calm them down, saying they do not expect any larger earthquake. They were sentenced to prison in October 2012.

Do you know the meaning of the Tsunami terms “Inundation” and “Runup” ?
During post-tsunami field surveys, inundation and runup measurements are taken to describe the tsunami effects. Inundation is defined as the maximum horizontal distance inland that a tsunami penetrates. Runup is the maximum vertical height above mean sea level that the sea surface attains during a tsunami. Actual tsunami wave heights can be measured from the amplitude of the wave signals seen on sea level or tide gauge instruments.

3 prefectures to draw up evacuation plan for Mt Fuji eruption (japan)
The prefectural governments of Yamanashi, Shizuoka and Kanagawa plan to formulate a prediction of the damage likely to be caused by lava flow, falling rocks and ash clouds as a result of a Mt Fuji eruption.
The predictions are to be used to draw up effective evacuation plans for residents of the three prefectures. Up to 750,000 residents would have to evacuate in Shizuoka and Yamanashi prefectures in the event of an eruption, according to an earlier government estimate.Click here to read more …

China, 1966 - Magnitude : 6.9 – 1000 people killed
More than 180,000 “rooms” collapsed and 276,000 were severely damaged in Hebei Province, with the most severe damage in the Ningjin-Shinhe area. At least 10,000 rooms collapsed and over 22,000 were heavily damaged in Shandong (Shantung) Province. Over 6,000 rooms and cave dwellings collapsed in Shanxi (Shansi) Province and some rooms collapsed in the Anyang area of Henan (Honan) Province. Some damage occurred at Beijing (Peking) and Tianjin (Tientsin). It was felt as far away as Hohhot and Nanjing. In the epicentral area, large fissures crisscrossed the ground and there were many sandblows. Embankments slumped into the Fuyang River. As with the Mar 07 quake, no no casualty figures were released, other than to say fewer people died than in the previous event. We assume that at least 1,000 people were killed in this earthquake based on the severe and extensive damage, despite the fact that it occurred in the afternoon, when most people would have been awake and better able to protect themselves.

This was the most destructive earthquake in recent African history. The damage appeared to center about Bundibugyo, a one-street township 42 miles from Fort Portal, near the Congo border. About 140 fatalities and hundreds of injuries were reported from Bundibugyo, Fort Portal, and Kichwamba. At Kamango, in the Congo, a chasm 8 feet wide and 1,000 feet long opened up in the ground. Immediate relief measures were greatly impeded by landslides which severed communications and blocked highways.

Earthquakes make gold veins in an instant
Scientists have long known that veins of gold are formed by mineral deposition from hot fluids flowing through cracks deep in Earth’s crust. But a study published today in Nature Geoscience1 has found that the process can occur almost instantaneously — possibly within a few tenths of a second. The process takes place along ‘fault jogs’ — sideways zigzag cracks that connect the main fault lines in rock, says first author Dion Weatherley, a seismologist at the University of Queensland in Brisbane, Australia.Click here to read more …

Animal behavior and earthquakes
The earliest reference to unusual animal behavior prior to a significant earthquake is from Greece in 373 BC. Rats, weasels, snakes, and centipedes reportedly left their homes and headed for safety several days before a destructive earthquake. Anecdotal evidence abounds of animals, fish, birds, reptiles, and insects exhibiting strange behavior anywhere from weeks to seconds before an earthquake. However, consistent and reliable behavior prior to seismic events, and a mechanism explaining how it could work, still eludes us.

New seismometer enables quake observations in all waters
A Japanese Agency has said it has developed an undersea seismometer that can withstand depths of more than 10,000 meters, enabling it practically to observe undersea quakes in all waters. The Japan agency for Marine-Earth Science and Technology said its instrument, covered in a pressure-resistant container, was installed at seven locations deeper than 6,000 meters — the furthest conventional seismometers can be placed in the Japan Trench in the Pacific, and obtained data in an experiment in December and January using the deep-sea probe ship Kairei.

An earthquake without a seismology report – or was it a sonic boom.
The linked article describes an analysis of a sonic boom with the characteristics of an earthquake. Earthquake-report.com gets regular I Have Felt It reports from people having felt an earthquake which was in fact a sonic boom. This is an example of such an earlier report.
Several news reports, for example from KREM and from KHQ, describe a bright flash in the sky with colors and in some cases followed by a boom or series of booms. Reviewing seismograms around 6:30 AM PST we find weak signals on several stations (fairly strong signal on station, DAVN). By picking the arrival times (marked with blue arrows on the attached seismograms) of these signals and knowing that sound travels about 325 meters/second in air we can invert the arrival times for a common source location and origin time. $$$$$ Read more ….

Does the earth opens during an earthquake ?
One of man’s persistent fears about earthquakes is that the Earth will open and swallow everyone and everything nearby. Shallow crevasses can form during earthquake-induced landslides, lateral spreads, or other types of ground failures. Faults, however, do not open up during an earthquake. Movement occurs along the plane of a fault, not perpendicular to it. If faults opened up, no earthquake would occur because there would be no friction to lock them together.

Scientists Identify Trigger for Explosive Volcanic Eruptions
Scientists from the University of Southampton have identified a repeating trigger for the largest explosive volcanic eruptions on Earth.
The Las Cañadas volcanic caldera on Tenerife, in the Canary Islands, has generated at least eight major eruptions during the last 700,000 years. These catastrophic events have resulted in eruption columns of over 25km high and expelled widespread pyroclastic material over 130km. By comparison, even the smallest of these eruptions expelled over 25 times more material than the 2010 eruption of Eyjafjallajökull, Iceland. $$$$$ Read more …

Ninety people killed.
A gigantic landslide blocked the Bartang River, destroying Usoy and several other villages in a sparsely-populated area, creating Sarez Lake (Sarez Kol, Sarezskoye Ozero). The landslide created a dam 4-5 kilometers thick and 703-788 meters (2,306-2,585 feet) high, with an estimated mass of 7-10 billion metric tonnes (about 7.7-11 billion short tons). This natural dam is roughly 10 times higher and about 1100 times the mass of the Madison Canyon Slide that created Earthquake Lake after the Hebgen Lake, Montana quake of August 18, 1959. That landslide created a dam up to 73 meters (240 feet) high and had an estimated mass of 73 million metric tonnes (80 million short tons).

The interior of Antarctica has icequakes. The icequakes are similar to earthquakes, but occur within the ice sheet itself instead of the land underneath the ice. Our polar observers have told us they can hear the icequakes and see them on the South Pole seismograph station, but they are much too small to be seen on enough stations to obtain a location.

ER Comment : Great work from this boy but this application can and may only be used as a gadget. But, also a gadget can be useful especially for massive tsunami generating earthquakes along the coast. It will however save only very few lives in case of a devastating shaking earthquake because the damage, injuries and fatalities will occur in the direct epicenter area and there is NO TIME left to be alerted. The earthquake will strike within 1 or 2 seconds. The app needs more time to be activated.
The Mexican authorities have also an official similar alert which is triggered by the Mexican seismology service.
California politicians want to have such an alert as soon as possible.
Japan has it already some time.
The most interesting benefit of such alert system is halting or reducing the speed of trains, stopping elevators at the next level etc.
Once again great to be alerted at 200 km from the epicenter that some shaking will occur, but not affective at all to resist or escape major devastating earthquakes.

There is no such thing as “earthquake weather”.

The changes in barometric pressure in the atmosphere are very small compared to the forces in the crust, and the effect of the barometric pressure does not reach beneath the soil.

Japan, 1978 - Magnitude : 6.7 – 21 people killed
Southern Honshu was struck by a damaging earthquake, centered midway between Oshima Island and Izu Prefecture. Twenty-one people were reported killed; 119 injured; and four missing. Considerable damage was reported in the area, including many landslides, and damage was estimated to be about $76 million; maximum intensity was V (JMA). Tsunamis were reported at Oshima Island (35 cm), Tateyama (12 cm) and Shiono Misaki. This earthquake was preceded by a number of smaller shocks that were felt the day before and was followed by a number of aftershocks, many of which were in the 5.0 – 5.5 range.

Statewide quake in California may be possible after all
For decades, scientists have assumed the central portion of California’s San Andreas fault acts as a barrier that prevents a big quake in the southern part of the state from spreading to the north, and vice versa. As a result, a mega-quake that could be felt from San Diego to San Francisco was widely considered impossible.
But that key fault segment might not serve as a barrier in all cases, researchers wrote Wednesday in the online edition of the journal Nature. $$$$$ Read more …

Damage and injuries occurred in every department of El Salvador. Eight people killed in Guatemala. Felt from Mexico City to Colombia.

United Nations Office for Disaster Risk Reduction – Hyogo Framework for Action (HFA)
The Hyogo Framework for Action (HFA) is the first plan to explain, describe and detail the work that is required from all different sectors and actors to reduce disaster losses. It was developed and agreed on with the many partners needed to reduce disaster risk – governments, international agencies, disaster experts and many others – bringing them into a common system of coordination. The HFA outlines five priorities for action, and offers guiding principles and practical means for achieving disaster resilience. Its goal is to substantially reduce disaster losses by 2015 by building the resilience of nations and communities to disasters. This means reducing loss of lives and social, economic, and environmental assets when hazards strike. $$$$$ Read More

California, 1857 - Magnitude : 7.9 – 1 person killed
The largest historical earthquake in California.
One of the Largest Earthquakes in the United States
This earthquake occurred on the San Andreas fault, which ruptured from near Parkfield (in the Cholame Valley) almost to Wrightwood (a distance of about 300 kilometers); horizontal displacement of as much as 9 meters was observed on the Carrizo Plain. It caused one fatality.

USGS science conclusions are working on a safer world
A powerful magnitude 7.9 earthquake struck Alaska on November 3, 2002, rupturing the Earth’s surface for 209 miles along the Susitna Glacier, Denali, and Totschunda Faults. Striking a sparsely populated region, it caused thousands of landslides but little structural damage and no deaths. Although the Denali Fault shifted about 14 feet beneath the Trans-Alaska Oil Pipeline, the pipeline did not break, averting a major economic and environmental disaster. This was largely the result of stringent design specifications based on geologic studies done by the U.S. Geological Survey (USGS) and others 30 years earlier. Studies of the Denali Fault and the 2002 earthquake will provide information vital to reducing losses in future earthquakes in Alaska, California, and elsewhere.

About subduction faults
Subduction zones are found where one plate overrides, or subducts, another, pushing it down into the mantle where it melts. An example of a subduction-zone plate boundary is found along the northwest coast of the United States, western Canada, and southern Alaska and the Aleutian Islands. Subduction zones are characterized by deep-ocean trenches, shallow to deep earthquakes, and mountain ranges containing active volcanoes.
